Blockchain can be a double edge sword. For some it can be a savior and some can be a killer. If you live in a country where a single citizen have barely any rights then blockchain can be a savior for you. This is where the saying banking the unbank applies. If you live in a country where you are the oppressor then blockchain can be a killer for you. I think blockchain in a way equalizes each and everyone but the thing is not everyone knows about blockchain, so even if blockchain can be your savior if you dont have knowledge or access to it then it is no help to you.
